Friends,
How to add Array of PictureBox controls to the Listbox ? My requirement is to display N number of images from the directory to the PictureBoxes on Windows form.
I am able to generate N number of picture boxes dynamically, but how to add them in a listbox control with scroll bar option.
I cannot use ListView as the image size limitation is only (256,256)
Please suggest some option to achieve it.
Regards,
VHK
ListBox doesn't accept child controls. What you can do is:
Add the Images to the ListBox.Items directly (or wrap them in a helper class if you want to add ie. the filename of the image)
Set the DrawMode to OwnerDrawFixed
Handle the DrawItem event to paint the corresponding image

Can you help me, I have a TabControl but I can not put the image below the text carries the headertab any ideas?
I use c# and winform
To assign Images to TabPages, you can drop an ImageList on designer and add images to it, then select your TabControl, select ImageList property and set it to the image list you created. Then select TabPages property and edit tab pages, for each tab page, select an ImageIndex to show image before text.
But you should know TabControl doesn't have built-in support for images below/above text automatically, To do so, you should use Owner Drawn TabControl. You should set DrawMode property to OwnerDrawFixed and then handle DrawItem event and draw tab pages yourself.
I want to implement a combobox (in drop-down list mode), where the items in the drop-down list are 64 in height, but where the dropdown list item displays itself at normal height. The use case here is a list containing file names with an image thumbnail next to it. I want the ordinary display to be normal height with a small thumbnail, but much larger thumbnails in the associated drop-down list.
When I've tried modifying the item height, the entire combobox is set to accommodate it, not just the drop-down list (entirely reasonably I suppose).
Is this possible?
Thanks for any tips.

I believe you need to make the Combobox owner drawn and use the Measure event.
The Event passes the MeasureItemEventArgs which includes the index to the item being drawn.
Here is a sample from Microsoft's documentation Combobox.Measure event
Perhaps you could use the OwnerDraw mode? This example shows an example with a custom height separator item, but i guess you could apply the same principle to all items in the combo-box..

I'm doing project in windows forms using c#.
I want to show an image in the listview subitems.
For eg:-
There is a listview having 3 Columns (Column 1 is Roll number,Column 2 is StudentName,Column 3 is StudentPhoto) .I can use the ListViewItems to add Items in the ListView.
Adding First items to the ListView,
ListViewItem item = new ListViewItem("101");
item.SubItem.Add("Robin");
SampleListView.Items.Add(item);
Now i'm having difficult in Showing StudentImage in the 3rd column,Can anyone help!
Note:
Also i have ImageList assigned to SampleListView.
ListView does wrap the native list view control from common controls of Windows. This control does not directly support images on subitems. You need to set the listview it to owner draw to let you handle the drawing.
Luckily others have done this already. On CodeProject there is a good one.
How can I create a ListBox control on my Winforms application that has images in an orderly fashion, just like it holds text?
I'd like the images to appear like this:
Maybe I don't even need to use a ListBox. Maybe there's a better control out there for this purpose? Thanks!
You possibly want an owner-draw list box. There's an example on the MSDN page for the DrawItem event.
Load all your images into an imagelist, using a unique key for each image, such as a filename. Make sure you set the imagelist imagesize to the size of the images.
Set the listview LargeImageList property to the imagelist you loaded.
Assign the imagekey property of each listview item to the key that matches its image in the imagelist.
Set the listview view style to view.largeicon.
Profit.
How do you add a image to a tab label on a tab control?
Just like this:
But on a normal tab page like this:
I understand to do this you need to a add a Imagelist and make a index of the images to be used but I haven't found any examples searching on google. Any help?
Add an ImageList control to the form (this should be in the Toolbox). Add the images you want to the image list by going to the properties tab and set the Images property.
Then go to the properties for the tab control; and in the ImageList property select the image list you created in the previous step, then in the TabPages property open up the Tab Page Collection Editor (by clicking the button) select a page, then you want to set the ImageIndex property to the index of the image from the image list.
